The circuit in Figure 1 measures both the true-rms value and the rectified average value of an ac signal. This design uses two low-cost ICs in SOIC packages and consumes only 180 µA of quiescent ...

On infrequent occasions, I am asked to design a circuit to measure the RMS value of a current or voltage for some kind of power measurement. Since the work I do is hardly unique, I thought some of you ...

How many times have you poked around a circuit with a digital multimeter (DMM), read an AC voltage value, then gone on your merry way? Ever wonder if your meter is giving you peak value, average value ...

The variety of test and measurement products available today can boggle the mind. From the mundane to the exotic, these instruments can practically lead you by the hand. However, if you don't have a ...

Although SPICE can be a powerful tool, there are pitfalls in relying solely on simulation. To avoid unpleasant surprises, it's imperative that a SPICE simulation be anchored to a detailed ...
